3. Licence termination
3.1. If your licence to use the software is revoked for any reason, you must cease its use immediately and deinstall the software and delete all data that is related to the software from all machines. Exceptions regarding the deletion of data may apply when there is a specific legal reason that prohibits you from doing so.
3.2. Non-compliance of the user with material contractual obligations, terms, or agreements automatically results in the immediate revocation of the licence.
3.3. You may withdraw from this agreement by permanently ceasing the use of the software and irreversibly removing any and all data related to the software from all of your devices.
3.4. Some stipulations may survive the termination of the agreement. This notably applies to limitations of liability and damages, proprietary rights, choice of law and jurisdiction where applicable, as well as warranties and disclaimers and more.
4. User obligations and safety guidelines
4.1. The user must read and adhere to the guidelines for the use of the software in order to avoid and minimise the potential for damages to hardware, software(*) and work, as well as life, body and health.
4.2. These guidelines do not present an exhaustive list of all the safety measures the user should implement. They are an addition to the implementation of and adherence to safety measures that are to be expected from the user when working with audio software in general.
4.3. Safety guidelines
(a) You must test the software extensively at low volume first. Start off with your speakers physically disabled and observe the output meters of your plug-in host when processing audio with the software. Only enable your speakers and later increase the volume after you have made sure that the resulting output does not contain any volume spikes or other excessively loud content.
(b) Always keep the maximum volume levels below the threshold for potential hearing damage. Ensure that your software(*) environment has a safety mechanism that mutes, or at least limits, the audio output if a set volume level is exceeded. Make sure that you are at all times able to quickly mute the audio by hardware/mechanical means if necessary, for example by turning off your speakers entirely.
(c) Take special caution when adjusting parameters while audio is playing, including switching presets. This may lead to significant sound artefacts and is not recommended. If you do so anyway, do this at very low volume levels and take special care to limit the possible output.
(d) If there are significant changes in your listening environment, such as using different hardware, software(*)/software updates or using a different plug-in host, you must repeat the initial steps, checks, and other precautions that are mentioned in this section to ensure safety.
(e) In order to avoid loss of work, you must make regular backups of your work. Always make a backup of your projects before incorporating the software.
(f) You must periodically check whether there are more recent versions of the software and keep the software up to date. You may check for updates by visiting the appropriate pages on our website https://convexaudio.com or via the “Info” panel from inside the plug-in.
5. Privacy notice and authorisation process
5.1. This privacy notice is an addition to the privacy policy that can be found on our website at https://convexaudio.com/privacy-policy/.
5.2. The authorisation (or “registration”) process of the software on a new device requires an active and stable internet connection at the time of authorisation. The connection to the server may be logged by the server host, IONOS Group SE, and their privacy regulations apply. A server connection is also established when you check for updates via the “Info” panel in the plug-in. Internet connections may incur charges by your internet provider.
5.3. Some of the data that is sent to the server for the authorisation process is stored on the server to ensure proper use of the licence. The legal basis for this is the EU General Data Protection Regulation (on the basis of Article 6 Para. 1 lit. b) GDPR).
5.4. Making significant changes to your device may require you to re-authorise the software. You need to authorise the software on every new device that you want to use the software on.
5.5. You may need to download the latest version of the plug-in for the authorisation process to work. If there are changes to the authorisation process, any changes and corresponding instructions will be published on our website or sent to you by e-mail.
6. Intellectual property

You are still bound by the obligations and limitations of this EULA, our GTC, as well as any other applicable legal documents. However, your right of use is limited to the very minimum that is required to perform a technical compatibility check. After having performed such a check, you may not use the software further by any means. If you no longer have the intention to purchase a regular licence for the software from us or 14 days have passed since you installed the software, you must deinstall the software and delete any related data immediately and permanently. Note that the software’s functionality is severely limited until you purchase a regular licence and authorise your device.
